ELECTRIC-LIGHT SHADE.

Specification of Letters Patent.

Patented Jan. 10, .191 1.

Application filed July 26, 1910. serial No. 573.915.

To all whom/it "mag concern:

Be it known that I, CLIFFORD C,- CARPEN- rnn, a citizen of the UnitedStates, residing at Seattle, in the county of King and State oflVashington, have invented certain new and useful Improvements inElectric-Light Shades, of which the following is a specification.

The object of this invention is to provide an exceedingly simple andinexpensive form of shade adapted to be readily attached to and detachedfrom the sockets to which ordinary electric light bulbs are secured.

The invention involves particularly a shade comprising a suitableopaquebody which is carried detachably by a simple form of clamp, the latterbeing conveniently arranged for engagement with the light socketaforesaid.

For a full understanding of the invention, reference is to be had to thefollowing detail description and th accompanying drawings, in whichvFigure 1 is a View showing an ordinary electric light inventionsupported thereon, the shade being shown in section; Fig. 2 is anelevation of the shade and its supporting member, the clamp membersbeing omitted; Fig. 3 is a plan view showing more particularly the clampdevice; about on the line H of'Fig. 2, and Fig. 5 is a modification,being a View similar to Fig. 1.

Throughout the following description and on the several figures of thedrawings similar parts are referred to by like reference characters.

In the drawings, 1 denotes the socket adapted to receive the e ectriclight bulb 2, the latter being adapted to be screwed into the socket inthe customary way and coin taining the usual filament The shadeattachment comprising this invention composed of four essential parts,namely, the shade member shown at 4, a supporting member 5 securedthereto, and two clamp members 6.

It is contemplated that the shade 4: may be made of any suitable opaquematerial or substance, but said shade is preferably formed from sheetmetal and is of concavoconvex-*form in cross section. An opening isformed at the central portion of the shade by pressing the metaloutwardly as shown at.

4 and the supporting number 5 consists of bulb and socket having the-Fig. 4 is a section taken a length of wire, the lower end of which 'is jbent upwardly to provide a hook 7 which passes through the centralopening of the shade 4. The hook 7 is of peculiar shape in order that itmay be so engaged with the shade 4 as to prevent loosencss of the latterwhen suspended adjacent to the light by means of the member At its upperportion, the hook 7 is formed with a bend 7', providing a recess on theinner side of the hook, and adjacent to said recess the metal ormaterial from which the shade 4 is made is formed with a U-shapedprojection 4", the latter being preferably pressed out Wardly from themetal as shown clearly in the drawings. .Vhen the shade 4 is supportedon the member 5, the bond 7 of the hook 7 engages over the lower portionof the projection 4.", and the upper extremity of the hook is seatedbetween the sides of said upward displacement of the shade from themember 5, as well as lateral play of the shade.

The supporting member 5 has its upper end passing through coinplementalpivot lugs integral with each of-the clamping members 6, therebypivotally connecting said clamping members. The upper peripheral portionof the shade 4 is cut out or recessed as shown at 8 to provide aclearance space for the finger pieces 6 of the clamping members 6. Thecut out portion of the shade may also serve as a clearance space toreceive the body of the socket 1 in' the manner shown in themodification in Fig. 5 should it be'dcsired that the shade illustratedin said figure be permitted to assume the position shown.

, The stmcture illustrated in Fig. 5 is substantially'thc same ashereinbefore described excepting that the clamping members and the shadeare arranged in slightly different relative positions, and the hook 7 ofthe supporting member 5 is of slightly diflerent form, having theprotuberance 5 to engage the central apertured portion of the shade 4 tosubserve the rigidity of theconnection between the supporting wire ormember 5 and said shade.

A spring 9 is interposed between the finger pieces 6 of the clampmembers 6 to normally cause the latter to move toward one another.

Having thus described the invention,what is claimed as new is: v

1. A shad: attachment of the class deprojection, thereby preventingaccidental shade comprising a Wire having one end bent to form a hookpassing through the aperture, a clamping device connected with said suporting member, the shade being provide with a projection engaging thehook of the supporting member to prevent play of the shade when mountedthereon.

2. A shade attachment comprising a shade provided with an aperturetherein, a supporting member consisting of a piece of wire having oneend bent upon itself to form a hook passing through the aperture, saidhook beingprovided with a depression in its length, the shade beingformed with a U shaped projection pressed. outwardly therefrom and thecurved end of which is received in the recess of the hook' preventingaccidental displacement of the shade from the supporting member, thesides ofthe U- shaped projection being arranged at opposite sides of thehook tonevent lateral play of the shade,suspende thereon, and clampingmembers pivotally mounted on the upper end of the supporting memberaforesaid, the shade being recessed at its upperportion adjacent to theclamp members to Ol'IIla clearance space as speclfied.

In testimony whereof I afiix my signature in presence of two witnesses.
